Here is an editorial I found from a recent edition of the Aiken Standard in South Carolina. It does not properly understand tire oxidation, as it assumes that since a tire is exposed to oxygen on the outside of the tire, oxidation isn't too much of an issue. That is not necessarily the case. The majority of oxidation (of the rubber, steel belts, etc. that does the damage to a tire and ultimately causese failure) occurs as oxygen permeates through the tire and comes in contact with the tire interior. That is a major conclusion on page 7 of the Ford Nitrogen Study conducted by John Baldwin.
